py3: make i18n/posplit use absolute_import

wireproto: optimize handling of large batch responses Now that batch can be used by remotefilelog, the quadratic string copying this was doing was actually disastrous. In my local testing, fetching a 56 meg file used to take 3 minutes, and now takes only a few seconds.

cleanup: replace False identity testing with an explicit token object The recommended way to check default value (when None is not as option) is a token object. Identity testing to integer is less explicit and not guaranteed to work in all implementations.

devel: officially deprecate dirstate.write without transaction argument When we introduce the develwarning, we did not had an official deprecation API and infrastructure. We can now officially deprecate the old way with a version deadline.

devel: officially deprecate update without destination When we introduce the develwarning, we did not had an official deprecation API and infrastructure. We can now officially deprecate the old way with a version deadline.

devel: fix a typo in a deprecation warning Credit goes to Sean Farley for spotting it.

devel: officially deprecate old style revset When we introduce the develwarning, we did not had an official deprecation API and infrastructure. We can now officially deprecate the old way with a version deadline.

check-code: handle py3 open divergence open() really wants an encoding attribute

check-code: switch to opener

check-code: handle range/xrange divergence

check-code: fix py3 complaint about \NNN being invalid unicode

hghave: switch from iteritems to items With this, test-hghave.t passes on python 3. Four features fail because mercurial still is not py3 safe: absimport cacheable hardlink defaultcacerts But that will be resolved automatically eventually.

hghave: matchoutput needs to use bytes for regexp file output is bytes in py3, so we need each regexp to be bytes

revset: make dagrange preserve order of input set Unlike range, dagrange has no inverted range (such as '10:0'). So there should be no practical reason to keep dagrange as a function that forces its own ordering. No performance regression is spotted in contrib/base-revsets.txt.

tests: mark test-check-pyflakes.t as requiring hg1.0+ hg does not yet run with py3, so if you try: ./run-tests.py --local test-check-pyflakes.t ... it will try to run the local hg, which does not work and thus, hg locate will return no output to stdout (and stderr is sent to /dev/null). If you do: ./run-tests.py --with-hg=~/bin/hg test-check-pyflakes.t Then it should work, if your hg is new enough to have a locate command (hg0.6 does not have locate).

dirstate: make backup methods public They are called from outside of dirstate anyway and I want the localrepo to use them too.

check-code: add a rule banning `env -u`

subrepo: use unset instead of env -u to fix test on BSDs (issue5229)

graphmod: partial edge styling Allow for a style to only apply to the last N lines (for positive N) or everything but the first N lines (for negative N) of the section along the current node. This allows for more subtle grandparent styling. So from the default: $ hg log -G ... o Lorem ipsum dolor sit :\ amet, consectetur : : adipiscing elit, sed : : do eiusmod tempor : : o : incididunt ut labore | : et dolore magna | : aliqua. Ut enim ad | : minim veniam, quis |/ o nostrud exercitation : ullamco laboris nisi : ut aliquip ex ea : commodo consequat. : o Duis aute irure dolor | in reprehenderit in ~ voluptate velit esse cillum dolore eu to $ hg log -G --config "experimental.graphstyle.grandparent=2." ... o Lorem ipsum dolor sit |\ amet, consectetur | | adipiscing elit, sed . . do eiusmod tempor . . o | incididunt ut labore | | et dolore magna | | aliqua. Ut enim ad | | minim veniam, quis |/ o nostrud exercitation | ullamco laboris nisi | ut aliquip ex ea . commodo consequat. . o Duis aute irure dolor | in reprehenderit in ~ voluptate velit esse cillum dolore eu or $ hg log -G --config "experimental.graphstyle.grandparent=1:" ... o Lorem ipsum dolor sit |\ amet, consectetur | | adipiscing elit, sed | | do eiusmod tempor : : o | incididunt ut labore | | et dolore magna | | aliqua. Ut enim ad | | minim veniam, quis |/ o nostrud exercitation | ullamco laboris nisi | ut aliquip ex ea | commodo consequat. : o Duis aute irure dolor | in reprehenderit in ~ voluptate velit esse cillum dolore eu or $ hg log -G --config "experimental.graphstyle.grandparent=-2!" ... o Lorem ipsum dolor sit |\ amet, consectetur ! ! adipiscing elit, sed ! ! do eiusmod tempor ! ! o | incididunt ut labore | | et dolore magna | | aliqua. Ut enim ad | | minim veniam, quis |/ o nostrud exercitation | ullamco laboris nisi ! ut aliquip ex ea ! commodo consequat. ! o Duis aute irure dolor | in reprehenderit in ~ voluptate velit esse cillum dolore eu

pure: write a really lazy version of pure indexObject On PyPy this version performs reasonably well compared to C version. Example command is "hg id" which gets faster, depending on details of your operating system and hard drive (it's bottlenecked on stat mostly) There is potential for improvements by storing extra as a condensed struct too.

dispatch: always load extensions before running shell aliases (issue5230) Before this patch, we may or may not load extensions for shell aliases depending on whether the command is abbreviated or not. Loading extensions may have useful side effects to shell aliases. For example, the pager extension does not work for shell aliases. This patch removes the code checking shell aliases before loading extensions to give the user a more consistent experience. It may hurt performance for shell aliases a bit without chg but the correctness seems worth it. It will also make the behavior consistent with chg since chg will always load all extensions before running commands.

httpclient: update to upstream revision 2995635573d2 This is mostly Python 3 compat work thanks to timeless.

crecord: call prevsibling() and nextsibling() directly The 3 classes for items used in crecord (uiheader, uihunk, uihunkline) all have prevsibling() and nextsibling() methods. The two methods are used to get the previous/next item of the same type of the same parent element as the current one: when `a` is a uihunkline instance, a.nextsibling() returns the next line in this hunk (or None, if `a` is the last line). There are also two similar methods: previtem() and nextitem(). When called with constrainlevel=True (the default) they simply returned the result of prevsibling()/nextsibling(). Only when called with constrainlevel=False they did something different: they returned previous/next item regardless of its type (so if `a` is the last line in a hunk, a.nextitem(constrainlevel=False) could return the next hunk or the next file -- something that is not a line). Let's simplify this logic and make code call -sibling() methods when only siblings are needed and -item() methods when any item would do, and then remove the constrainlevel argument from previtem() and nextitem().

dispatch: add fail-* family of hooks The post-* family of hooks will not run in case a command fails (i.e. raises an exception). This makes it inconvenient to hook into events such as doing something in case of a failed push. We catch all exceptions to run the failure hook. I am not sure if this is too aggressive, but tests apparently pass.
